This document specifies a method for exposing plastics to concentrated solar radiation using reflecting concentrators to accelerate the weathering processes. The purpose is to assess property changes produced after specified stages of such exposures. The reflecting concentrators used in these exposures are sometimes referred to as “Fresnel reflectors” because in cross-section the array of mirrors used to concentrate the solar radiation resembles the cross-section of a Fresnel lens. General guidance concerning the scope of the ISO 877 series is given in ISO 877-1.

NOTE 3 For the purpose of production control, test methods other than those specified in this document can be used.

 

This document specifies the heat flow measurement method of the solar irradiation penetration ratio of paint films used for roofs and outer walls of buildings, structures, equipment or facilities situated outdoors and exposed to solar irradiation.

 

This document specifies the methods commonly available for separating adhesively bonded joints enabling repair and improving recycling. This document applies to adherends made of metallic and non-metallic inorganic material, plastics including both filler-containing and fibre-reinforced types, wood and wood-based materials, coated materials, adherends of natural and polymeric fibres as well as paper and cardboard.

 

This document provides terms and definitions, general principles, detection strategies and analytical methods for cell line identification of mammalian cells in the field of biotechnology. It also specifies general requirements and key considerations for method selection, quality control parameters, data analysis and reporting in cell line identification. This document is applicable to routine cell line cross- contamination testing in the fields of basic research, translational medicine studies and cell therapeutic product manufacturing. It is also applicable to cell line identity confirmation to prevent cell misidentification in academic and industrial laboratories, cell banks and manufacturing sites. It is primarily applicable to mammalian cells.

 

This document specifies geometrical and dimensional tolerances for plastic moulded parts including: This document is applicable to non-porous moulded parts made from thermoplastics, thermoplastic elastomers and thermosets of thermoplastics, made by injection moulding, injection compression moulding, transfer moulding, compression moulding and rotational moulding. This document is applicable to other plastic processes if agreed to by the contractual parties. Moulded part surface imperfections such as sink marks, undesired flow structures and roughness, as well as joint lines are not addressed in this document.

 

This document specifies a method for the determination of the axial crush resistance of wound paper and board cores.

 

This document contains requirements for the design, testing, inspection and marking of serially produced, refillable storage systems intended only for liquid hydrogen for land vehicle operation. These storage systems The scope of this document is limited to fuel storage systems containing fuel cell grade hydrogen according to ISO 14687 type II grade D. The content is mainly focused on heavy duty vehicles for road operation but may also be applied to on-board fuel storage systems for other road vehicles, industrial and other land vehicles with due consideration of appropriate service conditions.

 

This International Standard specifies a method, based upon linear elastic fracture mechanics (LEFM), for the determination of mode I fracture toughness of structural adhesive joints at high loading rates. It determines mode I fracture toughness by testing at high loading rates using double cantilever beam (DCB) specimens of the same or dissimilar materials bonded by adhesive. Wedges are inserted or pulled out at high speed between the pins in the load-block to open the end of the DCB specimen. This test method supplements the quasi-static tests ISO 25217 and ISO 22838 and extends the coverage to higher loading rates than these standards.

 

This document defines terms related to cell counting for biotechnology. It describes counting of cells in suspension (generally cell concentration) and cells adhered to a substrate (generally area density of cells). It provides key considerations for general counting methods (including total and differential counting, and direct and indirect counting) as well as for method selection, measurement process, and data analysis and reporting. This document is applicable to the counting of all cell types – mammalian and non-mammalian (e.g. bacteria, yeast) cells. Several sector/application-specific international and national standards for cell counting currently exist. When applicable, the user can consult existing standards when operating within their scope (specific measurement techniques and/or applications).

 

This International Standard specifies test specimens and procedures for fatigue testing at ambient conditions, under repeated tensile loading, generating cross-tension loading to the bonded plates of carbon fibre reinforced plastics (CFRPs) to metal assemblies. The specimen undergoes cyclically stress, comprising an alternating stress on a static stress which represents the mean stress. This allows for estimating the safety condition regarding the fatigue resistance of joints. The method is intended for testing bonded plates used in bonding CFRPs to metal assemblies with adhesive or other specified methods.

 

This document specifies a method of measuring the smoothness of paper and board, called the Bekk method. The smoothness of a wide range of papers and boards may be measured by this method and it is especially recommended for smooth papers and boards. However, for very smooth samples, measurement times may be impractically long. This method is not recommended for material greater than 0,5 mm thick or very permeable papers and board, since the amount of air passing through the test piece can influence the result.

 

This document specifies three methods for the determination of ash from raw rubbers, compounded rubbers and vulcanizates. The methods are applicable to raw, compounded or vulcanized rubbers of the M, N, O, R and U families described in ISO 1629, except that: This document does not cover the interpretation of the ash results as to the inorganic chemical content of a compound or vulcanizate. This is the responsibility of the analyst, who has to be aware of the behaviour of rubber additives at elevated temperatures.
